jpmschweitzerandClaude Opus 5.5 5a45c69280 docs(meta): D-258 amended — rung 0.5 measured, storage not forced (T-1212, T-1213)
The 2026-08-06 amendment ruled: build the un-summarisation as a pure function,
measure it, and open the storage question only if the numbers force it. They
do not.

tests/rung_cost_bench.rs (ignored, run with --release) times the real derive on
Ferrath at the ladder anchor: the whole-body solve 114 ms once per body, one
served canvas 118 / 141 / 175 / 175 ms at Global / Region / District / Quarter.
Storage that could serve Region is ~71 GB for one body; a layer at the record's
own sizing holds only Global's resolution, the rung that least needs it.

The amendment also states what the conservation gate actually protects: the
reliefmap D-258 names as the biome input is read by no server code, so the
"summary" is the derive's own uncomposed verdict. Whether it should become an
input is left for Jeroen. T-1214/T-1215 are annotated, not cancelled.
